Silicon production by the reduction of quartzite in furnaces is accompanied by copious dust
emissions containing a high proportion of valuable silica (86%, on average). It is of great …

Quartz (SiO 2) is the main silicon source for production of metallurgical grade silicon in
submerged arc furnaces. During heating in the furnace, quartz will first transform to other SiO …

This article deals with material research of selected types of quartz and quartzites in order to
determine the priority of their use in the production of ferrosilicon and pure silicon …

Silicon production by carbon reduction of silica-containing raw materials is performed in ore-
thermal furnaces. The process proceeds at high temperatures (above 2,000 C). Consumers …

The mechanisms in the carbothermic production of silicon have been examined in this
report. Through the investigation of a pilot scale furnace as well as five small scale induction …

Silicon carbide (SiC) is an essential intermediate product formed during the smelting
process of metallurgical-grade silicon (MG-Si), and its production efficiency is a key factor in …

This paper explored the effect of different grinding media on the property improvements of
petroleum coke with rare earth carbonate. The experimental results were discussed in …

This article describes elements of the know-how of using carbon electrodes produced using
the technology of molding around a rod when smelting silicon metal. Application of our know …

The growing scarcity of conventional oil resources has intensified the focus on shale oil,
known for its abundant reserves. Nevertheless, in the process of shale oil retorting, a …
